Unless you buy an upscale gaming or some other specialized PC, chances are the keyboard and mouse that comes with your new computer is boringly and often uncomfortably basic, and more than likely wired via separate USB cables for both devices. If you spend a lot of time typing and mousing around, you might want to consider something easier on your wrists and fingers, such as the Logitech MK850 Performance Wireless Mouse and Keyboard Combo we’re reviewing here today. The MK850 lists for $100, but is frequently sold for $80.

If you’ve done any shopping around, then you already know that the array of available products, either keyboards and mice sold separately or combo products, is dizzying. Not only does Logitech offer several combos, including the Wireless Keyboard K350 & Performance Mouse MX Bundle ($135), but so does Microsoft, such as its Sculpt Ergonomic Desktop ($130) and the Wireless Discomfort Desktop 5050 (which we’ll be reviewing shortly).

While many of these input peripherals have been designed to maximize comfort and convenience, the MK850 has the uncommon ability to pair with up to three separate computing devices and switch between them with the touch of a button.

Over the course of a day, many of us flip back and forth between two, sometimes three, computing devices, moving from the keyboard on a desktop to the virtual keyboard on a mobile device, and back again. Wouldn’t it be much simpler if you could switch between and enter data on these gadgets from the same keyboard? A while back, Logitech released such a solution, the K380 Bluetooth Keyboard ($30), which let users flip between multiple devices with the touch of a button.

While a terrific idea, a shortcoming of the K380 is that it doesn’t provide a way to hold your smartphone or tablet upright as you type. Logitech corrected via a groove, or gutter, carved into the top section of its Bluetooth Multi-Device Keyboard K480 ($30). Both the K380 and the K480 let you pair up to three devices and switch between them easily, but each has its limitations. The K480’s groove, for instance, is big enough to hold only one mobile device, and the keyboard itself has no number pad.
